As a result of my last posting, a couple asked what the F5 memory is used for. Basically, there are four 'modes' available for saving data, which is downloaded via Photo Secretary: Mode Contents Approx Rolls ---- -------------------------------------------------- ------------ A Shutter Speed, aperture, lens' focal length, 78 maximum aperture, frame count B A plus: Year/month/day/hour/minute/second 36 C B plus: Imprint data between frames 12 D C plus: Metering system, exposure mode, sync mode, 10* EV difference in Manual exposure mode, exposure compensation value * (39 rolls, without MF-28) Data for modes B and C can only be stored when using the MF-28. >From what I've been told, the F5 comes with 2mb, only available expansion is to 4mb, which should double the number of rolls stored for the above modes. -Mike Baranowski
